摘要： A data encoding method apparatus in which the volume of arithmetic-logical operations for calculating the total number of bits required for encoding for adaptive bit allocation in the variable length encoding system for expediting the processing. In the data encoding apparatus for encoding and subsequently variable length encoding the input data, spectral data obtained on orthogonal transform coding are routed to a block floating circuit 403 for normalization and re-quantized in a quantization circuit 404 depending on the bit allocation number information from a bit allocation calculating circuit 406 so as to be then variable length encoded by an encoding circuit 407 and outputted at an output terminal 408. The bit allocation circuit 406 refers to a table memory circuit 409 in which re-quantized data domain is divided at boundary points corresponding to code length transitions in order to calculate the total number of bits required for encoding using a smaller volume of arithmetic-logical operations for the purpose of adjusting the number of allocated bits.

摘要： According to the present invention, for encoding input signals, the input signals are transformed into frequency components, and the frequency components are separated into a first signal composed of tonal components and a second signal composed of other components. The first and second signals are encoded respectively, and code strings for transmission or recording are generated on the basis of encoded signals resulting from first and second encoding. For example, only the first signal is encoded and the code string is caused to include partial information strings grouped so as to have common values on the basis of at least one of reference parameters pertaining to the signal separation and parameters pertaining to the first encoding. Thus, more efficient encoding than in the conventional technique can be realized.

摘要： A signal encoding method and apparatus for encoding an acoustic signal, a recording medium having the encoded signals, a method for transmitting the encoded signals, and a signal decoding apparatus for decoding the encoded signals, are disclosed. With the encoding apparatus, an attack portion detection circuit detects an attack portion of the waveform acoustic signal where the waveform elements of the waveform acoustic signal rise sharply. A gain control circuit controls the gain for waveform elements at least upstream of the attack portion using a gain control amount adaptively selected from plural gain control amounts specified by a pre-set power of 2. A forward orthogonal transform circuit transforms the waveform acoustic signal into plural spectral components. A normalization and encoding circuit normalizes, quantizes and encodes the gain control information an plural spectral components. With the encoding apparatus, the encoding efficiency may be improved without complicating the construction, while the pre-echo may be suppressed effectively.

摘要： In this invention, an approach is employed to carry out blocking of an input signal to transform the blocked signals into spectrum signals to divide the spectrum signals into a plurality of units to normalize them thereafter to implement variable length encoding to all or a portion of the spectrum signals to output the variable-length encoded signals along with normalization coefficient and the number of re-quantization bits of each unit, wherein an upper limit is provided with respect to the number of bits per each block of a signal to be encoded and outputted to compulsorily change, in a block for which the number of bits above the upper limit is required, normalization coefficient of at least one unit thereafter to re-quantize and entropy-encode a corresponding signal to output the encoded spectrum signal, thereby permitting hardware scale to be smaller as compared to the conventional apparatus without depending upon unevenness of the number of bits by variable length encoding. In addition, efficient encoding and decoding can be carried out in a form such that influence from a viewpoint of the hearing sense is small.

摘要： A method and apparatus for encoding input digital data by high-efficiency encoding, a method for transmitting the encoded information and a method and apparatus for reproducing and decoding the transmitted information, are disclosed. For encoding, an input signal is forward orthogonal transformed into spectral signals using a windowing function for forward orthogonal transform having a shape A. For decoding, the spectral signals are inverse orthogonal transformed using a windowing function having a shape B different from the shape A. The degree of concentration of the energy of the spectral distribution may be raised and efficient encoding may be achieved even in case of modified DCT (MDCT) wherein the windowing function needs to satisfy a pre-set constraint.
